The first connecting portion 11 and the reflecting structure 3 can be connected by caulking, and the first connecting portion 11 has a tapered hole 111 penetrating through both sides thereof, and the tapered hole 111 is used for the cable 2 to pass through.
The second connecting portion 12 is fixedly connected to the first connecting portion 11, and the second connecting portion 12 has a stepped hole 121 penetrating both sides thereof for the cable 2 to pass through. As shown in fig. 9, a junction position between the small-diameter section 1211 (i.e., the section of the stepped hole 121 having the smaller diameter) of the stepped hole 121 and the large-diameter section 1212 (i.e., the section of the stepped hole 121 having the larger diameter) of the stepped hole 121 forms a limiting step 1213, and the limiting step 1213 is used for limiting a fixing position of the cable 2 when passing through the stepped hole 121, so as to ensure consistency of the fixing position of the cable 2.
